If a command is put into the VIEW_NODE, it is going into the
ENABLE_NODE as well. This is especially true for show commands.
As such if a command is in both consolidate it down to VIEW_NODE.

This patch improves zebra,ripd,ripngd,ospfd and bgpd so that they can
make use of 32-bit route tags in the case of zebra,ospf,bgp or 16-bit
route-tags in the case of ripd,ripngd.
It is based on the following patch:

* zclient.c: prefix length on router-id and interface address add
messages not sanity checked. fix.
* */*_zebra.c: Prefix length on zebra route read was not checked, and
clients use it to write to storage. An evil zebra could overflow
client structures by sending overly long prefixlen.
Prompted by discussions with:

Since recently zebra uses only the ZEBRA_REDISTRIBUTE_* messages
to advertise redistributed routes to its clientes. Now the old
ZEBRA_IPV*_ROUTE_* messages are only used for client->zebra communication.

The new TE functions will always print out a warning
that TE has not been configured on an interface. This

This is a rather large mechanical commit that splits up the memory types
defined in lib/memtypes.c and distributes them into *_memory.[ch] files
in the individual daemons.
The zebra change is slightly annoying because there is no nice place to
put the #include "zebra_memory.h" statement.
bgpd, ospf6d, isisd and some tests were reusing MTYPEs defined in the
library for its own use. This is bad practice and would break when the
memtype are made static.
